Senior embedded developer in MCU, Linux, and Android based systems.Designed and developed reference implementation of professional audio platform on Android OS. Wrote SELinux policy, startup services, C++ Binder IPC, etc. into vendor image build for custom Audio HAL. Integrated into Qualcomm's ALSA audio front end for Hexagon DSP proxy port on QCS8250.Worked within Amazon team as embedded technical lead for in-home Zigbee hub for smart window product. Configured Buildroot with custom packages. Designed Python application logic running on embedded Linux, connected to AWS IoT via MQTT. OTA firmware update, cloud logging, etc. Wrote dev tools for cert and firmware generation across DEV, UAT, and PROD.Ported multiple projects to new MCU architectures and vendor SDKs driven by supply chain shortages. Tracked and solved several memory corruption and multithreading issues caused by hardware and compiler differences. Collaborated remotely with multidisciplinary teams and clients to meet requirements.

Oversee all software development, primarily on embedded systems. Envision end user experience, product feature sets, and creative solutions on power limited microcontrollers.Software designs from scratch on bare metal, RTOS (ThreadX, FreeRTOS), Linux, & Windows. Design and code base libraries and APIs used across multiple projects and platforms.Collaborate with Electronics Engineers to create hardware platforms with appropriate capabilities to support software feature sets. Diagnose hardware issues, custom board bring-up and validation using oscilloscope, logic analyzer, etc.Custom bootloaders and firmware update tools, low level device drivers, hardware abstraction layers, encryption, code signing, peripherals (I2C, SPI, ADC, UART, GPIO, ETH, SDRAM, SD Card), MPU / L1 Cache / DMA coordination, POST (RAM test, ROM test, Watchdog test), displays (MIPI DSI, LCD/TFT, frame buffers), hardware accelerated CRC, AES, etc.Product documentation, customer support and presentations, etc. Interview, on-board, manage and mentor junior engineers.
